I think the declaration for uint16_t is missing. You should have
#include <stdint.h>
somewhere before using uint16_t. Otherwise, the compiler thinks you are
trying to use the old K&R rule that an identifier that hasn't been given a
type defaults to int. So in
void Delay(uint16_t);
the compiler thinks you are trying to declare a function prototype that
takes a parameter named "uint16_t" (since it doesn't know this was
supposed to be a type rather than a parameter name) that has an implicit
type of "int".
